3d car configurator; Koenigsegg CCX

Hi.
I have been working on small 3d car configuration demo; this is still work in progress, but I would like to get feedback from some of you.
Model used in this demo is from Google Warehouse, but it was almost entirely remodeled and re-textured (especially interior, witch was quite low res and lacked any textures).
For shaders and lighting I used Marmoset Skyshop, and background HDRI maps are free samples from HDRI hub.
Things I have to do are:
- finish interior textures
- add emblems all over the car (interior and exterior)
- add some extra features like display of cars dimensions and some info about car.
- add door opening sound and maybe option to turn on engine
And that would be it for this demo; I don't plan to cram in whole bunch of features for now, and my programming knowledge is quite limited, so some things I can't implement yet....
